is provided whereby. the slight pressure of a release button will cause the slider to move quickly along the fastener elements in opening the fastener.

In the accompanying drawing, I have shown for purposes of illustration one embodiment which my invention may assumein practice. In the drawing:

Fig. 1 is a side elevation view illustrating a small pouch equipped with my invention;

Fig. 2 isa longitudinal central section through the fastening device;

Fig. 3 is a cross-section through the fastening device;

Figs. 4 and 5 are perspective views of a fastener element as modified to accommodate the' automatic opening device;

Fig. 6 is a cross-section through the spring motor; and

Fig. 7 is a section on line 7-7 of Fig. 6.

*The fastener illustrated comprises a pair of fiexible stringers herein fabric tapes 6, '7 by which the fastener can be Conveniently attached in any article, such as the tobacco pouch of Fig. 1. In the example shown, the'fastener ex- V tends along the upper edge of the pouch. While the fastener may be of any of the known types which are actuated by a slider, the one illuson the market and more particularly described in the 'patent to Sundback 1,219,881. It comprises fastener members 9 attached in uniformly spaced relation to the edges of the stringers 6, -7. The fastener elements each have a projection 10 and a' recess '11, and when the fastener is closed, the projections on one side interlock with the recesses on the opposite side. The fastener is opened and closed by means of a slider 12 A which is adapted to' be manually operated by a pull tab 13. The function of the slider is to bring the fastener elements into engaging relation or to spread them apart as it moves along the fastener in one direction or the other. In order to accommodate the fiexible connecting trated is similar to the type commonly found member, each of the fastener elements is provided with'a notch 14, in its front face, so that when the fastener is closed, the notches form a longitudinally extending passage.

The motive means for actuating the slider comprises a manually controlled spring motor device having a casing 15, which is preferably soldered or otherwise fixed at 16 to the bottom stop member 17 of the fastener. The Construction of the spring motor has not been illustrated in detail since such a device is commonly known. It comprises merely a stationary casing 15 and' a rotary case 18, housing the spring 19 on which is wound the fiexible member 20. V This may be a wire or cord which' extends through an opening 21 in the casing 15 and through an opening in the bottom stop member, through the longitudinal passage formed by the slots 14 and is connected to the slider in any suitable manner. In the illustration, the wires extend through the thick neck connection of the slider and may be Secured by a nut or solder as indicated at 22. The spring is tightened by pulling the slider to the closed position. It is held in such 'position by any conventional releasable retaining means such as the spring hook 22 the point of which engages in holes 23 in' the outer disk of the case or drum 18. The spring normally pulls the hook into one of the holes and when it is desired to open the fastener automatically it is merely necessary to push on the button 24 whereupon the spring will cause the drum to rotate and the slider to move.

While I have in this application shown and described one embodiment which my invention may assume in practice, it will be understood that this is merely for the purposes of illustration and description and that various other forms may be devised within' the scope of my invention asdefined in the appended claims.

What I claim as my invention is:

1. The combination of a separable fastener, a slider for opening and closing the same, and means carried by the fastener remote from but connected to the slider for mechanically actuating the same in at least one direction.

2. The combination of a separable fastener and slider movable along the same for controlling opening and closing of the fastener, means carried by the fastener remote from but connected to the slider for automatically moving the slider 105 to open the fastener.

3. The combination of a separable fastener, slider movable along the same for opening and closing the fastener, motive means carried by the fastener remote from but connected with the 3 slider. for mechanically movng the slider in at and slider for opening and closing the fastener,

a relatively stationary spring motor mounted adjacent one end of the fastener and having a flexible connection with the slider for mechanically actuating it in one direction.

6; The combination of a separable fastenen and slider for opening and closing the fastener, a spring motor having a stationary mounting adjacent one end of the fastener and having a flexible connection with the slider for mechanically actuating it in the opening direction.

7. The combination of a slide fastener, a slider movable along the same for opening and closing the fastener, and resilient means remote from but connected to the slider adapted to have energy stored in it by closing movement of the slider and upon releaseto'move the slider in opening direction automatically. v

8. The combination of a separable fastener having flexible stringers and projecting interlooking members on the edges of said stringers adapted to interlock when intermesh'ed, a slider movable along said elements for engaging and disengaging the same, motive means having a stationary mounting adjacent one end of said fastener and having a flexible connection with said slider extending through the 'fastener elements whereby the slider may be mechanically actuated in at least one direction.

9. The combination of a separable interlocking i'astener having cooperating elements adapted to interlock when intermeshed, each of said elements having a notch in the front facethereof to afiord longitudinal passage for a flexible member when the fastener is closed and a slider for opening and closing the fastener, a spring motor mounted adjacent the lower end of the fastener, a flexible member connected to the spring motor and through said longitudinal passage and having a connection to said slider whereby energy is stored-in said spring motor by the closing movement of said slider, and a manual release for said spring motor to move the slider automatically in opening direction.
